I do that on my development machine (Asus P2B-DS, bios 1012B). When the MPS 1.4 support is disabled, the BIOS presents an MPS 1.1 table that overloads all PCI interrupts onto the ISA bus. - Tor Egge To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
